What happens when tire pressure drops? Alliance Tires Field Day in Sicily puts it to the test
Live demonstrations show how tire setup influences traction, slippage, soil impact and fuel efficiency in real conditions
Caltanissetta, Italy, May 2026: Can something as simple as tire pressure make a visible difference in the field—and even have a measurable impact on fuel consumption? At a recent Alliance Field Day in Sicily, that question was answered not with theory, but with tractors at work.
On May 9, 2026, dealers, farmers and contractors gathered at the San Cataldo industrial area near Caltanissetta, where a series of live, side-by-side demonstrations showed how tire pressure and construction affect traction, slippage, soil behaviour and overall operational efficiency.
Similar demonstration formats in other European markets have already highlighted how strongly tire setup can influence efficiency. At a recent Alliance Field Day in the UK, controlled comparisons showed fuel consumption differences of up to 20% depending on tire pressure and configuration. Building on this approach, the Sicily event focused on making these effects visible under local field conditions.
Rather than focusing on product presentations, the day was designed to make one thing clear: what happens in the soil when tire setup changes.
From pressure to performance: making the impact visible
One of the central demonstrations featured the Agriflex+ 372, a VF (Very High Flexion) tire engineered to operate at lower inflation pressures through flexible sidewalls and an enlarged footprint. Used in a traction-focused demonstration at low pressure, the setup allowed participants to observe how changes in footprint influenced wheel slip, traction and soil interaction under load.
As slip was reduced and traction improved, more of the tractor’s power was effectively transferred to the ground instead of being lost through wheel spin—an effect that can have a direct impact on fuel consumption and overall efficiency in practical operation.
A separate compaction demonstration also visualised how different inflation pressures influence the way load is transferred into the soil. By reducing soil compaction, the correct tire setup helps preserve soil health by supporting water retention, root development and long-term field productivity.
The Agri Star II, featuring Alliance’s Stratified Layer Technology (SLT), was showcased during ripping operations, highlighting its traction and performance under demanding field conditions.
The recently launched Agri Nova, introduced in early 2026, was also on display. Designed as a next-generation R-1 bias tire for light-to-medium duty tractors, it features a high-density lug pattern with a distinctive 3-angle design to enhance traction while maintaining driving comfort. A wider footprint helps distribute load more evenly, supporting reduced soil compaction, while integrated mud breakers contribute to effective self-cleaning in the field. The tire is developed to offer a balanced performance in both field operations and road transport.
A long-standing partnership in the spotlight
Beyond the technical focus, the event also marked a 30-year collaboration between Alliance and Lirio Orlando, reflecting a long-term partnership built on close cooperation and a deep understanding of local agricultural conditions.
To recognise this milestone, Alliance presented Orlando with a commemorative plaque during the event—highlighting a relationship that has grown alongside the agricultural sector in the region.
Local expertise, real conditions
The field day was organised with the support of distributor Olpneus, a long-established tyre distribution specialist with a strong presence across Sicily and growing operations in central Italy. With extensive experience in the agro-industrial sector and close relationships with local farming businesses, Olpneus played a key role in ensuring the demonstrations reflected the practical realities of Southern Italian agriculture. Technical partner Tomasella Macchine Agricole supplied the tractors used during the event.
Their involvement ensured that the event was not only about products, but about how those products perform under the specific conditions of Southern Italian agriculture.
By bringing theory into the field, the Alliance Field Day turned a widely discussed topic—correct tire pressure—into something farmers could actually see, measure and experience for themselves.
